Determination of fat and water contents in human from "SAT"-MRI sequences using automatic image segmentation

An interactive segmentation tool for quantifying fat in lumbar muscles using axial lumbar-spine MRI

“…The pixel signal intensity (SI) variations between the muscle and the fat region can be used to distinguish the fat region from the muscle region [1,2,5,12,25]. By using an appropriate threshold, the pixels in the fatty regions of the segmented lumbar muscles are detected [22], [23].…”

“…To date, in the broader area of fat deposition in muscles per se, qualitative [1,3,[5][6][7][8][9][10] as well as quantitative approaches [4,[11][12][13][14][15] have been adopted.…”

Fat quantification in MRI-defined lumbar muscles

“…The pixel signal intensity (SI) variations between the muscle and the fatty region can be used to distinguish the fatty region from muscle region [2], [3], [6], [9], [11]. By using an appropriate threshold, the pixels in the fatty regions of the segmented lumbar muscles are detected [4], [5].…”

“…Qualitative [1], [3], [7], [9], [12], [14], [16] as well as quantitative approaches [8], [11] are used for the study of fat deposition in muscles. In the qualitative approach [1], [9], the fat infiltration in the lumbar multifidus muscles is visually graded, using the standard scale of 0, 1 and 2 [1], [9].…”
